It is a short acting beta 2 agonist.
How does Tiotropium Bromide work?
It is a cholinergic (muscarinic) antagonist
Why are corticosteroids given for acute episodes of respiratory disease?
They inhibit the production of cytokines to reduce bronchiole activity

Histoxic hypoxia
Tissue cells are unable to make use of the oxygen available to them (ex. cyanide poisoning)
Hypoxic hypoxia
Oxygen pressures are too low to saturate hemoglobin
Stagnant or distributive hypoxia
Blood flow to tissues is either too low or unevenly distributed
Hemic or anemic hypoxia
Lack of functional hemoglobin to carry enough oxygen to tissues
Bronchial spasm activated by what system?
Parasympathetic nervous system
What causes bronchial smooth muscle contraction?
Acetylcholine
Which drugs can cause wheezing?
ASA, non-selective beta blockers, ACE inhibitors
What does ECMO do?
Pumps blood outside the body to a machine that adds oxygen and removes carbon dioxide
